I thought I'd the same issue on my main rig, but not the other night. First game I got 56.01 on the qual. (And eventually beat my high score in newer MAME, by ten points, of 65030.) However, tonight on this machine, my gameroom MAME rig, it still runs weird. No effects running or anything. Both machines are XP32, and I'm running HLSL on my main rig. I dunno....
